Dear powerpc porters,
The glibc 2.41-1 (version in experimental) testsuite fails to pass on
powerpc:
| FAIL: math/test-float-log10
| original exit status 1
| testing float (without inline functions)
| Failure: Test: log10_downward (0x1p+0)
| Result:
| is: -0.00000000e+00 -0x0.000000p+0
| should be: 0.00000000e+00 0x0.000000p+0
| difference: 0.00000000e+00 0x0.000000p+0
| ulp : 0.0000
| max.ulp : 3.0000
|
| Test suite completed:
| 4 max error test cases,
| 148 input tests,
| - with 600 tests for exception flags,
| - with 140 tests for errno executed.
| 1 errors occurred.

The full build log is available there:
https://buildd.debian.org/status/fetch.php?pkg=glibc&arch=powerpc&ver=2.41-1&stamp=1738281295&raw=0
I have tracked down the issue to this GCC bug:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=67771
The issue is specific to powerpc and doesn't affect ppc64 or ppc64el as
they have a baseline that includes the fcfid instruction. Could you
please have a look?
Thanks
Aurelien
